It is interesting that Shulchan Orech is included as one of the Steps of the Seder. I mean, since when did Jews need to be commanded to eat?! The answer, I think, hearkens back to what we mentioned in the step of Rachtza: one can eat a meal as a pure physical necessity or desire or one can take the physicality in the meal and elevate it to something spiritual.
The Ma’ainah Shel Torah asks the question of how it is possible to split the Hallel that we say at the Seder (half after Maggid and half during the step of Hallel)? Isn’t the eating of an entire meal in between the two halves considered a hefsek (an impermissible interruption)? The answer is that when we properly eat our meal, in a manner that raises it from the physical to the spiritual, the meal itself is really a continuing praise of Hashem and therefore is not an interruption at all.
